Normally, there is a wire labeled electric antenna that can also serve as a remote since when you turn on the car radio, it sends a signal to the antenna motor to deploy automatically. So, by using this wire, the amplifier will turn on just like the antenna would.

Good evening,
It's all well and good to say it's a Sony Xplod, but that doesn't give us the exact model; this information can be found either above or below the car radio.
Then we might be able to tell you more.
Best regards.
